For some time now I’ve felt the need to read through a good book on Christology–first, to push back the horizons of my ignorance; second, and more importantly, to feed my soul. In his introduction to Athanasius’ On the Incarnation, C. S. Lewis wrote:
I tend to find the doctrinal books often more helpful in devotion than the devotional books, and I rather suspect that the same experience may await many others. I believe that many who find that ‘nothing happens’ when they sit down, or kneel down, to a book of devotion, would find that the heart sings unbidden while they are working their way through a tough bit of theology with a pipe in their teeth and a pencil in their hand.
This has certainly been true for me as I work my way through The Person of Christ by Donald Macleod. I honestly don’t know how many people would share my experience in this book–sometimes you “happen” to come along the right book at just the right time. Regardless, Macleod’s has been that book for me which is one of the reasons I’ll periodically pass on some of the more challenging and/or meaningful portions here.
Here, then, is an excerpt from the chapter “Christ, The Son of God” on the relevance of Jesus’ transfiguration (pipe & pencil not included):
…[the transfiguration] has an on-going ministry. For Jesus, the trauma is past: he has entered into his rest. For us, it is not past. We are still struggling and suffering. To that situation the transfiguration still speaks, because it discloses not only the glory eternally possessed by the Lord, and not only the glory for which, as incarnate Mediator, he was destined, but also the glory of his people . . . The transfiguration showed not only what he would become but what we would become. The New Testament makes this connection explicitly. We are to be where he is (Jn 17:24). Our bodies are to be conformed exactly to his (Phil 3:21). We, in him, are to become sharers in the divine nature (2Pet 1:4). For Jesus on the Mount, this vision of what lay beyond the cross, not only for himself but for his people, would have been an immeasurable encouragement.
A. M. Ramsey relates this to the twin concepts, opsis and theiosis. Opsis is the spiritual vision which beholds the glory of the Lord. Theiosis is the transfiguring process which results: we are changed into the same image (2Cor 3:18), transformed by the renewing of our minds (Rom 12:2), and one day we shall be like him, because we shall see him as he is (1Jn 3:2). This goes back to the core of God’s own redemptive determination: to conform all his people to the image of his Son (Rom 8:29). Yet, as the sequel to the transfiguration shows, neither opsis nor theiosis goes on in ideal circumstances. We have to go down from the Mount to the demon-possessed valley. It is there that we must practice opsis; and only there that we can experience theiosis.
